Does this set of data have any outliers?

Data: 1, 2, 2, 4, 6, 6, 7, 8, 9, 10, 12, 13, 16, 16, 18.

no or yes

Outliers are numbers that are noticeably smaller or larger than the other numbers. For example: 1,2,3,8,9,10,11,88,13. 88 is the outlier because it is so much larger than the other numbers. Another example is: 67,70,72,73,76,12,80. 12 is the outlier because it is so much smaller than the other numbers. Get it?

I say no, there are no outliers.
